1. A method of indicating potential tampering with a security system component, the security system component including a camera lens, the method comprising:

  • receiving an analytic alarm indicative of defocusing of the camera lens;

    receiving data from an accelerometer;

    receiving data from a light sensor; and

    using a computing device to analyze the analytic alarm indicative of defocusing of the camera lens, the data from the accelerometer and the data from the light sensor to determine whether tampering of the security system component has occurred, the analysis includes determining whether a predetermined acceleration threshold has been met at approximately a same time as;

    a change in lighting of a scene monitored by the camera lens; and

    the defocusing of the camera lens; and

    generating a qualified alarm signal when the analysis is indicative of tampering.
